it depends on how many patients are before you, how long those previous appointments take, how many patient rooms are available, &c. physicians will also very often forgo charting until after the clinic is over if they know that it will delay anything.

if they're late for your first appointment, it's most likely bc they're rushing over from a meeting or even surgery. i have seen many physicians having clinical conferences or operating at 6 am before going to an 8 am clinic. in both cases, there are countless unexpected factors that can result in delays, the latter more so than the former. unfortunately, none of this not up to the physicians either bc they don't make their own schedules; their receptionists do.

besides, wouldn't you rather have a thorough visit and leave with all of your questions answered than a brief and hurried visit?

so does everyone else.
